Use the "hanetconfig" command to set the multiple logical virtual interface definition function. For details about this command, see the execution examples in "7.1 hanetconfig Command".
GS linkage mode in a cluster configuration
When taking over the logical virtual IP address assigned to the logical virtual interfaces (shaX:2 to 64) of the GS linkage mode, it is necessary to set the parameter (logical_vip_takeover) beforehand. In this case, perform the following procedure.
Information
The logical virtual interfaces of the GS linkage mode are displayed differently depending on the OS.
RHEL7
When configuring the logical virtual interfaces on a virtual interface shaX, the logical virtual interfaces are shaX:2 to shaX:64.
RHEL8 or later
When configuring the logical virtual interfaces on a virtual interface shaX, the logical virtual interfaces are displayed as the secondary addresses of shaX by the ip command.
Add the setting of "logical_vip_takeover 1" to ctld.param. After that, restart the operating system and make the setting enabled.
/etc/opt/FJSVhanet/config/ctld.param
#
# HA-Net Configuration File
#
# Each entry is of the form:
#
# <param> <value>
#
observ_msg 0
observ_polling_timeout 180
max_node_num 4
logical_vip_takeover 1 <- Added |
Set the same logical virtual IP address between active and standby nodes for the logical virtual interfaces (shaX:2 to 64). Also, set the virtual interface where the logical virtual IP address is set to takeover interface (shaX:65) of clusters.
Example of setting up active nodes
# /opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0:2 -i 192.168.210.202 # /opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0:3 -i 192.168.210.203 # /opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0 # /opt/FJSVhanet/usr/sbin/hanetconfig print (Omitted..) |
Example of setting up standby nodes
# /opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0:2 -i 192.168.210.202 # /opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0:3 -i 192.168.210.203 # /opt/FJSVhanet/usr/sbin/hanethvrsc create -n sha0 # /opt/FJSVhanet/usr/sbin/hanetconfig print (Omitted..) |
Information
When setting up the communication target monitoring, it is not necessary to set a logical virtual IP address with the -i option of the hanetobserv command as a setting to monitor other nodes of PRIMECLUSTER. For the following examples, the settings for "192.168.210.202" and "192.168.210.203" are not necessary.
# /opt/FJSVhanet/usr/sbin/hanetconfig print
